Cadets from Earls Cove and Pender Harbour were ferried to Powell River each week for parades and exercises, with obvious hardships and inconveniences.
The corps was formed in 1978 after the Army Cadet League of Canada, BC Branch decided to form a cadet corps on the Lower Sunshine Coast, with Sechelt as its central base.
The corps was affiliated with the British Columbia Regiment (Duke of Connaughts Own) under the command of Major Trevor Goddard CD (ret’d) and became known as 2963 Royal Canadian Army Cadet Corps.
Major Goddard was joined by Robert (Bob) Sommerfield and Doreen Pihichyn, followed by Lt. Banjay, from Earls Cove.
Sponsorship was required to support the new Army Cadet Corps and at the October 16th, 1978 meeting of the Royal Canadian Legion Branch #140 (Sechelt) the formal presentation was made. The motion was moved and seconded at that meeting that the cadets would parade in the hall on Thursday evenings from 6-9pm.
The corps was officially stood up on January 15th, 1979 with the designation of 2963 Sunshine Coast Army Cadets.
In 1984, under the command of Captain Robert Sommerfield, and with the work of Capt Ron Biggs, the corps changed its affiliation to the Seaforth Highlanders of Canada, which came into effect on 1 April 1985. On the 4th of January 2001 the corps officially changed their designation to the 2963 Seaforth Highlanders of Canada RCACC
In 1998 the Freedom of the City was bestowed upon the corps by the District of Sechelt, in recognition of the commitment to the District.
In January of 2019 the corps celebrated its 40th Anniversary by exercising their Freedom of the City in a Civic Recognition Parade. The corps recognized the partnership that they shared with not only the Royal Canadian Legion Branch 140, but also with the District of Sechelt, the Town of Gibsons, the Sunshine Coast Regional District and its citizens for over 40 years.
